I found a sponsor who needs some of the d:l:p modules (and some more,
which will be of course contributed back). I found that most of the
packages there are in a pitiable state, so I'd like to give them some love.

So would someone add

<person userid="seife" role="maintainer"/>

please?

In case that nobody answers, you can issue a request as well, the syntax is
something like:
osc createrequest -a add_role seife maintainer devel:languages:perl
